BEAD HOLDER.

Application filed October 5, 1925. Serial No; 60,557.

This invention relates to building construction and more especially to methods and means for settin bead members and other kinds of strips in place on the walls,

as for instance corner beads and various kinds of bead moldings including baseboardl and picture moldings, such as shown in the accompanying drawings. Heretofore, for lack of a suitable tool or instrument, a great deal of time and attention by skilled labor has always been necessary for properly adjusting, trueing up and securing beads and moldings in place by manual means, whereas the present invention involves the use of mechanical lmeans in the form of an extensible tool or strip holding device adap'ted for ready adjustment, setting and o ration by a workman to hold any desired orm of bead member in place while it is being attached to the wall. i The main objects of the invention are to provide an improved method and means for positioning and holding beads, moldings and the like while they are being fastening in place; to provide an implement or tool of this character adapted for ready adjustment as to length, whereby it may be set rigidly between the floor and ceiling or between the walls of a room in proper relation to the desired position for the bead or Vmolding; to provide thereon ready means to assure proper trueing up of the device for vertical positioning; to provide readily adjusted fastening thereon for gripping the object to be set in place; to provide for siniultaneous release of said fastenings after the bead has been set in place and secured; and to provide such a tool adapted for ready and accurate use by the workman using the same.

An illustrative embodiment of this invention is shown by the accompanying drawings, in which 2-- Figure 1 shows an unplastered wall with a picture molding set in place and a baseboard molding being held in place by an instrument embodying this invention.

Fig. 2 is a side elevation of the device showing the use of the instrument for holding the corner bead in Vertical position.

Fig. 3 is a holding a picture molding or baseboard molding in place.

Fig. 1,1 is a sectionalview of the device plan of the device as used for taken on line 4-4 of Fig. 2 showing the device set in position for attaching a corner molding in place, this view being on a much larger scale than Figs. 1, 2 and 3.

Figs. 5, 6 and 7 are Sections taken on lines 5, 6 and 7 respectively of Fig-1.

Fig. 8 and Fig. 9 are sections taken on lines Sand 9 respectively of Fig. 2.

In building construction, where the walls are to be finished by plastering,.it is common practice to fasten in position before the plaster lis put on certain trimming members such `as corner beads, moldings, finishing strips and the like, and then to plaster around all'except the face part and to leave the back portions of the strips embedded in the finished Wall. In Figure l is shown a flush type grooved 'picture molding 10 near the top and a finishing strip 11 near the bottoml forv the baseboard portion 12 which may be of concrete while the upper part of the wall is'plastered, the finished surface 13 of the wall :being indicated by` dotted lines. In Figs. 2 and 4, is shown a corner bead 14 for forming and reinforcing aprotruding edge or corner part of the wall in a room having such a corner.

These trimming members 10, 11 and V14 and the like are usually made of thin sheet metal Vwhich is soinewhat fiexible. Hence it is necessary for proper alinement and for the sake of good appearance, to have the bead strips held positively at several points so as to be accurately positioned and properly alined when fastened. Moreover, since the rough walls-are likely to be somewhat irregular, the process of setting the strips in true position is' often highly exacting and requires a good deal of skill.

Accordingly, I have provided an 'adjustable length multiple grip holding device, which may be readily set in place in compression and held frictionally between the ceiling and floor or betweenopposite walls. A series. of alined clamps or-gripping. devices are attached all in like mannerto the supporting part or extensible bar of the device, so that to position a strip clamped in the holders is merely a matter of properly setting the support, the latter being rigid and straight throughout its length. j

Asiillustrated in the drawings, the support or ali'ning bar member 15 comprises a lower metallic tubular portion 16 preferably of square cross section and an upper correspondingly shaped bar portion 17 which fits snugly and telescopes in the member 16, and is secured in a more or less extended position by means ot' a setscrew 1G' which tits in the threaded hole 16" of member 16 and may be turned to engage in any of the various holes or dents 17' provided inthe member 17. l'he upper memberl 17 may be made as a smaller sized metal tube or as a solid wooden pole adapted to lit in the member 16. A bi'oad tlat friction hearing 17 is lixed on the upper end of section 17 to prevent unintend'ed turning of the pole on its axis.

As is shown in Fig. 8, a spring pressed length take-up rod o r foot member 18 is mounted in the lower end of the member 16. The rod 18 is provided with a collar 19 held adjustably by the set screw 19' (see Fig. 8) and is slidable lengthwise in the spaced bushing like stop members 20 and 21 and is prcssed outwardly by means of the coled compression spring between the adjusting rod collar 19 and the upper bushing 21, the bushings :20 and 21 being secured rigidly in .the post member 1G by screws 20' and 21' rcspectively and outward movement of said rod being limited by the stop Q0.

A series of bead olamps 23 have forked yolce portions 24 which fit embracingly on the square support members 1G and 17 and which may be elamped in adjustable mutually spaced relation by means of the thumb screw Qe't' iu the tips ot the fork arms 91". The yoke or body portion 21 has an extending fixed jaw 95, and pivoted in coactive relation thereto is a movable jaw 2G which is mounted on a pivot pin 27 and is pressed towards closed position by means of the torsion coil .spring 28. Each of the movable ja ws tor the several clamps may be opened imlependmitly of one another` but means are provided, as will be dcs'cribed, 'for siinultaneously opening all ot the clamps, so that the finishing strips 10, 11 or 11, or whatever kind ot strip is to bc set, may be readily locked in the clamps and then instantly released therefrom after it is tastened in place on the wall.

In order to etl'ect simultaneous opening of all the clamp jaws as above referred to, a square key shaft 29 is inserted through Similarly apertured eylindrical collar meinbers 30 which are held by said shaft between opposite walls of the hollowed shank portion of the clamp body 21 in alinement with the circular openings 31 in the said walls. Each collar 30 is provided with av headed arm member or screw 32 which engages a longitudinally slotted plate 33 attached loosely by the screw 31 to the rear end of the jaw 26. By reason of vthe slot 33', as shown in Figs. and T, any jaw may be opcned independently of the others. The. key rod 29 may be turned by any suitable wrench, or by a cross handle 20' set thcrein. This bar 29 is adjustable in length at the joint 29", as will be understood.

To prevent the strips 'from slipping in the jaws and to accomplish similar clamping relation at all points, stop members 255 are prtwided to bear against the tace ot the head. These stops 235i are held adjustably in the fixed jaws by shil'tinrr the holding.r serew 30 in the screw slot 257. The outer face ot the jaw 2:7 is recessed at 2.3' to aecommodate the head of serew ."lt (see Fig. 4).

In order to facilitat'e exaet Vertical setting of the device, a plumb line 10 is suspended at 41 on the jaw 25 of one of the upper clamps and a lower jaw is gage marked to show when the instrument is set square.

In use the Support member 15 is extended appropriately and set in position where it is held by the end thrust` exerted by the spring prcssed rod 18. The inishine` strips are held in the elamps and are quickly adjusted into proper position by aptly shiftinfz the post member 15, suitably moving either or both ends. In some instanees the strips, as for instance the corner head 14, Fig. 11, is nailed fast and then the plastering put on, or the strips may be held entirely by the support 1:3 until they are embedded in the plaster which soon sets rig' idly. lVhen the work is finished, the clamps 23 are opened by turning,r the square operating rod 20. Then pressure is applied lengthwise to the support 15 to eompress the spring :'22 and loosen the post for rcmoval.

Although several variations of' method and but one specific structural embodiment of this invention are hcrein shown and described, it is to he understood that numerous details of the construction shown and some of the details of the methods dcscribed may he altered or omitted without departinp; from the spirit of this invention as defined by the following claims.
